The existing patents CN201610508919 and CN201420779747 both disclose the use of (full vanadium) flow batteries as power equipment for electric vehicles to provide power for them, but none of the prior art involves the use of (full vanadium) flow batteries as power equipment in vehicles. How to manage the battery, if the battery cannot be managed correctly according to different application scenarios, the performance of the (all-vanadium) flow battery will be exhausted in the long-term frequent use of the vehicle, and it will also endanger the use of the vehicle Safety and even the life safety of users
[0005] The existing patent CN111516556A discloses a thermal management system for pure electric vehicles. This system can complete the waste heat utilization and heat management in the electric vehicle under different cooling and heating requirements. There is still a big difference in the temperature control and waste heat recovery of the transportable electrode solution

The invention relates to an all-vanadium redox flow battery management system which comprises an electrolyte temperature control device (4) and a central control device (6). The all-vanadium redox flow battery management system is characterized in that the central control device (6) can be programmed to drive the electrolyte temperature control device (4) to carry out unilateral alternate heat exchange on the positive / negative electrolyte according to the user requirements and / or other internal or external instructions.
Description
technical field [0001] The invention relates to the field of chemical energy storage battery management, in particular to a battery management method and system using an all-vanadium redox flow battery as a carrier of power equipment. Background technique [0002] In today's energy shortage and serious environmental pollution, under the global attention to energy security and environmental protection, vigorously developing economical, clean and renewable energy has become the general trend. [0003] Current new energy vehicles mainly use batteries such as lithium-ion, lead-acid, and nickel-metal hydride as power equipment. However, even batteries that have been improved by researchers all over the world are not satisfactory in terms of battery capacity, battery life, and charging time. [0004] As a new type of high-performance energy storage battery, the liquid flow battery, especially the all-vanadium redox flow battery, stores and circulates the positive and negative elec...
